Introduction to Linux - A Hands on Guide

This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I'm trying to make IPTV work on linux router that i made. Here's my setup: Athlon XP 2400+, two realtek lan cards and dlink DWA-552 (atheros 5416). On this hardware i have running alpine linux (kernel 2.6.30.10-grsec). I'm using hostapd to configure wireless access point. I've setup IGMP Proxy for lan(eth1) and wlan(wlan0). IPTV works fine on lan, but if i try to watch IPTV on wlan the whole network breaks down. VLC displays first couple of frames and then routers times out. When i kill VLC everything goes back to normal. I would really appreciate any kind of help. I'll provide any additional info necessary.

If I understood you right you have:
Computer with 2 ethernet cards + wlan card.
One eth0 you use for uplink to internet, second eth1 for local network and wlan card for wireless network.
You can use IPTV from wired LAN, but can't from wireless.

If I understood you right you have:
Computer with 2 ethernet cards + wlan card.
One eth0 you use for uplink to internet, second eth1 for local network and wlan card for wireless network.
You can use IPTV from wired LAN, but can't from wireless.

And how can you explain it. Where is the bridge mode enabled where isn't?
And why do you need bridge at all. Packets from your wireless LAN should go directly to eth0.

I need bridge because I want to treat wlan0 and eth1 as one device. I don't really need separate ip addresses for those two interfaces. But the problem is not the bridge. I had same results without the bridge. Just to make sure I've removed the bridge, once again got same result. Here's my new route -n

I don't know if this will help or introduce more confusion but here goes. M y eth1 (LAN card) is actually plugged in DIR-300 which acts as access point / switch. If i connect to DIR-300 using wireless IPTV woks fine. DIR-300 has a "Wireless Enhance Mode on/off" setting under multicast settings. If i turn "Wireless Enhance Mode" off then I get same result with DIR-300: VLC displays couple of frames and stops working meanwhile ping to DIR-300 increases and eventually times out. IPTV works on DIR-300 wired connection. So as far as I understand i need to turn on "Wireless Enhance Mode" (whatever that is) on my wlan0. Does anyone have an idea what "Wireless Enhance Mode" might be?

I suggest to find manual for DIR-300 and find out what is "Wireless Enhance Mode".
Because may be you need to do something similar on alpine-linux.

I'm guessing that "Wireless Enhance Mode" might be setting multicast rate to some value. On linksys routers and apple airport you must set multicast rate to 6mbps or something in order to make IPTV work. Unfortunately ath9k doesn't support iwpriv mcast_rate And i can't get madwifi driver to work (but that's a topic for another thread) Did anyone else encountered this problem?
